参数不在可选范围之内

What it means

Thrown by the Guilin University of Electronic Technology news route (deprecated) when :type (default 'gdyw') is not a key of the infos map (keys include zbgs 招标公示, xshd 学术活动). Same Chinese 'parameter out of range' message; throws before the got request.

Solutions

1. Use a documented type slug (e.g. gdyw, zbgs, xshd).
2. Confirm keys against the infos map at the top of lib/routes-deprecated/guet/news.js.
3. Do not mix slugs between guet and guat routes.

Example fix

// before
GET /guet/news/zhaobiao   // not a key
// after
GET /guet/news/zbgs         // 招标公示

const VALID = ['gdyw', 'zbgs', 'xshd' /* see infos in lib/routes-deprecated/guet/news.js */];
const type = ctx.params.type || 'gdyw';
if (!VALID.includes(type)) throw new Error(`参数非法. Valid: ${VALID.join(', ')}`);

const isType = (v: string): v is 'gdyw' | 'zbgs' | 'xshd' => ['gdyw', 'zbgs', 'xshd'].includes(v);

try { await fetch(route); }
catch (e) { if (/参数不在可选范围之内/.test(e.message)) listTypes(); else throw e; }

When it happens

Trigger: Request with a :type segment not in infos; `if (!infos[type])` throws.

Common situations: Slug typo, or confusing this university's slugs with guat (Guilin Aerospace) slugs which look similar. The path is built by stripping a leading '/', so even valid-looking strings won't resolve if not a key.
